Abstract:
Objective To evaluate different post-processing imaging techniques of multi-slice helical CT cholangiography (MSCTC). Methods Fourty-seven patients were suspected of bile duct disease by ultrasound, with no abnormality by ordinary CT. These patients then received MSCTC examination. The original images were post-processed at workstation. The result of post-processed images was compared with that of the laparotomy and surgical bile duct endoscopy. Results Procedures were successful in 45 cases. Thirty-one cases were found with choledocholithiasis. The specificity and the sensitivity of CT virtual endoscopy (CTVE) for choledocholithiasis group were high. Cholangitis and cholangiocarcinoma were detected in 3 each cases.Three cases were finally found to have gallbladder polypus, in which only CTVE provided the diagnosis. The diagnosis of bile duct disease made by ultrasound were finally excluded by CTVE. Conclusions KG1 The available post-processing methods are CTVE and X-proj, MPR is applicable for observing bile duct wall, it is valuable in the diagnosis of all kinds of bile duct disease. CTVE is better than other methods at displaying intraluminal structure.
